Hello Kasper,
Sorry, my question isn't clear.
Is there "fake" relicas of pulsar watches out there claiming to be genuine Pulsars?
Considering a P1 is a real treasure now a days or a solid gold model with box and papers can be a real collectors item... I guess a magnet switch or a led module isn't that hard to replicate now a days but in the 70s?...
